This. invention relates to improvements in printing devicesdand has particular referencetoa type barfor. use intabulating, v accounting, printing and other similar kinds ofqmachines.

An object ofthe ,invention vis ton-provide animproved. typebar. of. simple,- practical and inexpensive construotion, wherein provisionL is made for detachably. mountingthe type container on the bar proper for ready removal therefrom.

Another object is to provide a removable closure for theA type. container which willfacilitate the operations of mounting the type elements therein and their removal therefrom when replacements are required.

The above and other objects will appear more clearly from the following detailed description when taken in connection with the accompanying drawing which illustrates a preferred embodiment of the inventive idea.

In the drawing:

Fig. 1 is a fragmentary side elevation of a type bar and its container, showing the elements in assembled positions.

Fig. 2 is a similar view illustrating the container detached from the bar proper.

Fig. 3 is an enlarged vertical longitudinal section.

Fig. 4 is a transverse section on the line 4--4 of Fig. 1.

Fig. 5 is a similar section on the line 5-5 of Fig. 1, and

Fig. 6 is a perspective view of the removable closure for the type container.

The device of the present invention is especially suitable for use in record controlled tabulating machines wherein the type bars are operated to selectively position the individual type thereof in association with the platen of a printing mechanism, after which said type are actuated by a hammer or plunger to print the character thereof upon a record sheet.

In the drawing, the type bar 1 is fragmentarily shown and, in accordance with the present invention, its upper end is provided with an elongated bifurcation 8 which imparts a degree of resiliency to the portions forming said bifurcation that enables them to spread slightly and restore to normal as the type container 9 is attached to and removed from said bar in a manner to be more specifically described hereinafter.

The container 9 comprises an elongated body made of sheet metal the longitudinal edge portions I of which are bent over upon .the central portion of the sheet to form an enclosure for the type I I transversely mounted in the container for 2. Claims. (CII 101-405) sliding movementtherein and projecting through opposed openings I2l formed inthe edges of the body. spacedy lugs.v I3,y are` formed intermediate the ends ofy the-container and .interiorly thereof betweenfwhich one of .the types II. pass and said lugs Iareemployed as an .anchoring means for a singlelwire, spring idhaving a loop lI5 for insertion between saidlugs.. The springis formed by bending the wireupon itself` toprovde two nor- 'mallyaligned end portions IS.. When thctype II and. spring I4. are-in position, the latter is disposed inelongatedrecesses I'I formed in. edges of said type and the portions I6 of said spring contact and exert pressure against one end wall of each recess so as to yieldably retain each type in its normal position and restore it to said position after a printing operation.

When assembling the type in the container, the small ends thereof are inserted through the openings I2 and the spring III is then introduced through the open upper end of said container and adjusted to the position shown in Fig. 3 in which said spring retains the type within the container and, at the same time, permits them to slide therein when operated to print. After the parts are so assembled, a resilient closure member I8 comprising a strip of metal is placed in position to close said open end of the container. To do this, the ends of said closure are successively inserted into opposed slots I9 formed in the edges of the container contiguous to its open upper end and, in so doing, the lateral projections 20 of said closure, formed intermediate its ends, will engage in opposed notches 2l in the upper edges of the container body to present displacement of the closure. When in position, said member I8 is slightly bowed, as shown in Fig. 3, and this condition tends to retain the closure in its operative position from which it may be withdrawn whenever it becomes necessary to remove the spring 4III or one of the type II.

The lower portion of the container body forms a channel for receiving the bifurcated upper end of the bar I when attaching the parts together. A small guide stud 22 is provided near the entrance to said channel and is of the same diameter as the width of the slot formed by said bifurcation so that the stud will engage the edges of Y said slot and thus prevent relative lateral movements of the container and bar when the same are connected. A larger locking stud 23, secured inwardly of and in line with the stud 22, enters the bifurcation or slot 8 as the bar 'I is inserted into position and, in so doing, initially spreads the portions forming said bifurcation after which said stud engages in the opposed detents 24 in said portions which then restore to normal so as to frictionally maintain the container and bar in elements, a stud in said channel extending' from tainer having edge portions overlapping a central I portion to form a channel and said edge portions Y having instruck flanges constituting retaining l Al5Y said central portion, and a type bar insertible into` Y l said channel for engagement by said flanges and having a bifurcated end formed with locking.

means for cooperating with said stud to releasably retain said container on said bar.

2. A printing device Vcomprising a type container having edge portions overlying a central portion to form a channel having an entrance, and said edge portions having inturned anges constituting retaining elements, a studf extending fromsaid central portion and disposed in said channel adjacent said entrance, a second stud extending from said central portion in alignment with the rst named stud,vand a type bar having a bifurcated end insertible into said entrance and guided into said channel and into contact with said retaining elements by engagement of said rst named stud with the opposed inner edges of said bifurcated end, said type bar also having detents in said edges for receiving the second named stud to releasably retain said container on said bar.
